Spring-energized seals use metal springs (canted coil or helical) within PTFE or FFKM jackets to maintain contact in low-pressure or vacuum conditions. Ideal for subsea connectors and cryogenic tools, they operate from -200°C to 300°C. Progressive spring force adapts to wear and thermal cycling. In BOP rams, FFKM spring seals contain 20,000 PSI kicks. Low breakaway friction suits rota... https://globalsealstech.com/product-category/oil-gas-seals/downhole-completion-tools-seals/
